Distribution of sulfur and chlorine over Europe
Maps showing the mean concentration of sulfar and chlorine in air and precipitation over north western Europe in summer and winter have been constructed. Exess SO4—S has been computed on the basis of the assumption that chloride is a conservative property of sea spray particles and that there are no other sources for chloride than sea spray. Finally, maps showing the ratio of concentration air/precipitation for sulfur and chlorine are presented.DOI: 10.1111/j.2153-3490.1963.tb01401.x
Some aspects of the seasonal variation of carbon dioxide and ozone
An attempt is made to estimate the seasonal source function, Q , of CO 2 on the basis of data for the biosphere, provided by Lieth, and for other sources. The variation of soil respiration appears to be the most uncertain factor. The resulting CO 2 variations in the atmosphere are calculated for horizontal exchange coefficients, K , which vary with latitude. Comparison with observations given by Bolin & Keeling shows that the results are not very sensitive with respect to the assumed variations of Q and of K with latitude. Previous results on the 0 3 budget are used to calculate seasonal variations of tropospheric 0 3 for stratospheric injection rates, and K values which vary with latitude.…
Global ozone budget and exchange between stratosphere and troposphere
A survey of existing data reveals that tropospheric ozone is fairly uniformly distributed within the hemispheres, but that the hemispheres are well separated. Within the northern hemisphere representative data of tropospheric ozone exhibit a uniform seasonal variation the phase of which is delayed by about 2 months with respect to the injection into the troposphere. It is suggested that this delay is controlled by the rate of destruction of ozone within the troposphere. On the basis of this concept and additional reasonable assumptions it is possible to give a quantitative analysis of the ozone budget and of the seasonal variation of the exchange between stratosphere and troposphere.

The dynamics of tropospheric aerosols
After a brief review of the present knowledge of the Stratospheric sulfate layer, several possible mechanisms of formation are discussed in detail. A direct transport of low tropospheric particles into the stratosphere by convective clouds penetrating the tropopause is not very likely because these penetrations are not high enough and because of the chemical composition of the stratospheric particles.
